Installing Valve Extenders
Behold the much-maligned valve extender. It is blamed, cursed, and often hurled at many races. And yet, if only properly installed it would do it’s job so seamlessly that many would forget it’s very existence, and pump their tires in bliss.
So what are the secrets?
First, use liquid plumber’s tape. Plumber’s tape goes on threads to prevent leaks, but there is a paste version that is infinitely easier to use, requires far less dexterity, fine motor skills, and most importantly, patience.
Second, have the right tools handy; a pair of needle-nose pliers and a small allen wrench should do nicely.
Begin by gently twisting the valve into the fully open position. This will keep it from rattling shut inside the extender.
Next, apply the plumber’s tape putty to the threads immediately below the valve core. A small dab will do you, and spread it evenly around the threads.
Screw the valve extender onto the valve, and tighten. This can be done with the same needle-nose pliers, or in the case of Zipp and similar extenders, a very small allen wrench fits into the head of the extender.
Voila! One worry-free valve extender. Now you can be like me and laugh at all the bumbling fools cursing their valves, their pumps, and their very existence on race morning. I just hope they are in my age group.




What keeps the inner valve from rattling shut again? How long until you are trying to fish a long allen wrench down your extender to free it?
Hi Nick,
If you’ll, again gently, tighten the valve into the open position, then it won’t rattle shut.
So open the valve, and keep opening it until you gently force it with the pliers. If you’re really worried about it you could dab some superglue on it to keep it open.
Nick, use a dab of superglue or use the pliers to crimp the valve nut.
